Minimizing power consumption

Bangle.accelWr

I'm looking at the Accelerometer specification KX023.
the 0x18 is the CNTL1 register.
PC1 RES DRDYE GSEL1 GSEL0 TDTE WUFE TPE Reset Value
Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 00000000

I'm testing this :

Bangle.setOptions({powerSave: false});
NRF.setConnectionInterval(100);
Bangle.setPollInterval(400);
setTimeout(() => {
	Bangle.accelWr(0x18,0b00000000);
}, 2000);

inside a .boot1 file..
